X Rebirth Catalog Tool 1.10 is an official utility released by Egosoft that allows players to extract and compile the files used by X4: Foundations

Overview

X Rebirth Catalog Tool 1.10 (often abbreviated as XRCT or simply Catalog Tool) is a community-developed utility designed to unpack, browse, and manage the .cat catalog files used by X Rebirth. These catalog files are compressed archives containing the game’s core assets: 3D models, textures, scripts, UI files, sound effects, and configuration XMLs.

1. Enhanced Save Parsing Engine

Previous versions sometimes choked on heavily modded save files or those exceeding 500MB. Version 1.10 introduces a more robust XML parser that handles compression and corruption more gracefully. This means you can now load late-game empires with hundreds of capital ships without crashing the tool.
